The present application claims priority to U.S. Provisional Patent Application No. 60/761,985, filed Jan. 23, 2006 entitled “FAUCET TEMPERATURE CONTROL APPARATUS,” the entire disclosure of which is hereby incorporated by reference in its entirety.
Embodiments of the present invention relate to the field of automatic faucets and, more specifically, to a faucet having an automated turn on feature, and an automatic temperature control apparatus, system and a method.
Faucets which automatically turn on when a person places their hands in close proximity to the faucet, and off when the person removes their hands from the close proximity are known and have been installed in millions bathrooms, restrooms and washrooms. However, the temperature at which the water flows from the faucet is a preset temperature determined by, for example, the faucet manufacturer, installer of the faucet, maintenance personnel, a plumber, or the like. A person using the faucet may prefer the water be a temperature that is different from the preset temperature.
Embodiments of the present invention will be readily understood by the following detailed description in conjunction with the accompanying drawings. Embodiments of the invention are illustrated by way of example and not by way of limitation in the figures of the accompanying drawings.
In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. Therefore, the following detailed description is not to be taken in a limiting sense, and the scope of embodiments in accordance with the present invention is defined by the appended claims and their equivalents.
Various operations may be described as multiple discrete operations in turn, in a manner that may be helpful in understanding embodiments of the present invention; however, the order of description should not be construed to imply that these operations are order dependent.
The description may use perspective-based descriptions such as up/down, back/front, and top/bottom. Such descriptions are merely used to facilitate the discussion and are not intended to restrict the application of embodiments of the present invention.
The terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms are not intended as synonyms for each other. Rather, in particular embodiments, “connected” may be used to indicate that two or more elements are in direct physical or electrical contact with each other. “Coupled” may mean that two or more elements are in direct physical or electrical contact. However, “coupled” may also mean that two or more elements are not in direct contact with each other, but yet still cooperate or interact with each other.
For the purposes of the description, a phrase in the form “A/B” means A or B. For the purposes of the description, a phrase in the form “A and/or B” means “(A), (B), or (A and B)”. For the purposes of the description, a phrase in the form “at least one of A, B, and C” means “(A), (B), (C), (A and B), (A and C), (B and C), or (A, B and C)”. For the purposes of the description, a phrase in the form “(A)B” means “(B) or (AB)” that is, A is an optional element.
The description may use the phrases “in an embodiment,” or “in embodiments,” which may each refer to one or more of the same or different embodiments. Furthermore, the terms “comprising,” “including,” “having,” and the like, as used with respect to embodiments of the present invention, are synonymous.
In various embodiments of the present invention, methods, apparatuses, and systems for controlling the flow of one or more fluids are provided. In exemplary embodiments of the present invention, a computing system may be endowed with one or more components of the disclosed apparatuses and/or systems and may be employed to perform one or more methods as disclosed herein.
As stated the one or more objects may be one or both of a user hands. It will be understood that the one or more objects could be a first hand in the first predetermined region and the one or more objects could also be a second hand in the second predetermined region. In other words in some cases two different objects may be considered the one or more objects that may effect control of the flow of a fluid in accordance with various embodiments of the invention.
In various embodiments the water delivery arrangement 110 may further include a control module 42 which may be coupled with the mixing valve 32 and the main flow valve 32 for controlling one or more operating conditions of the water delivery arrangement 110. The operating conditions may be one or more from the group consisting of: a default temperature, a maximum temperature, a minimum time for the main flow valve 40 to remain open to allow water to flow to the outlet 30 upon detection of the presence of the one or more objects, and a maximum time for the main flow valve to remain open which may prevent wasting water.
In various embodiments the temperature of the fluid may be adjusted by, for example, mixing a source of hot fluid and a source of cold fluid in differing amounts thereby adjusting the temperature of a mixed flow. In various embodiments the fluid may be water, for example. The faucet may be disposed to flow into a basin or sink. In various embodiments various sensors may be proximity sensors, and may use various technologies including but not limited to infrared, electromagnetic, body heat detection and the like. In various embodiments the fluid temperature may be adjusted by predetermined increments. In other embodiments temperature adjustment may be continuous. In various embodiments the temperature may be limited to a predetermined maximum temperature, limited by factors including but not limited to, environmental, cost or safety factors.
In such embodiments a person may approach the basin 56, and put one or both hands under the faucet 10 to turn the water on. The water may begin to flow at a starting, or default, temperature. Then with the flow started the user may move one, hand near the first proximity sensor 18 to warm the water up, or move one hand near the second proximity sensor 22 to cool the water down. In various embodiments the rate of warming or cooling may be determined by the amount of time the user's hand is near the first or second proximity sensors 18/22. In various other embodiments warming or cooling may be determined by the user moving his or her hand. In one embodiment the rate of warming or cooling maybe determined by the rate at which a user moves his or her hand. In various embodiments if the user removes the hand from under the faucet for a predetermined length of time the temperature of the flow may be reset to the starting or default temperature. The flow may also stop. The predetermined length of time and the default temperature may be considered operating conditions and may be adjustable. Other operating conditions may also be adjustable.
In various embodiments according to the invention a faucet may be adapted such that upon an object being positioned in a second predetermined region the temperature of the fluid may change, and upon the object being removed the temperature of the fluid will return to a default or predetermined temperature. For, example a user of various embodiments according to the invention may place one or both hands in a first predetermined region, to turn a flow on which may start at a default or starting temperature. Then the user may place a hand in a second predetermined region to increase the temperature. Upon removing the hand from the second predetermined region the temperature may one of: stay at the adjusted temperature; gradually decrease to the default temperature; or rapidly, and/or immediately decrease to the default temperature. In various embodiments the temperature of the fluid may change by a predetermined amount depending on a length of time an object is in a second region.
Various embodiments in accordance with the invention may include a method including:
reacting to a presence of one or more objects within a first detection zone of a first sensing arrangement by opening a first valve and allowing a mixed fluid to flow;
sensing the presence of the one or more objects in a second detection zone; and
adjusting a mixing valve based on the presence of the one or more objects to adjust relative components of the mixed fluid to change at least one characteristic of the mixed fluid.
With various embodiments the method the mixed fluid may be water and the at least one characteristic is the temperature of the water. Or in various other embodiments the least one characteristic is one from the group consisting of:
sweetness, bitterness, caffeine content, alcohol content, acidity, alkalinity and the like. Various embodiments may be used to adjust concentrations of dry or powered materials.
Although certain embodiments have been illustrated and described herein for purposes of description of the preferred embodiment, it will be appreciated by those of ordinary skill in the art that a wide variety of alternate and/or equivalent embodiments or implementations calculated to achieve the same purposes may be substituted for the embodiments shown and described without departing from the scope of the present invention. Those with skill in the art will readily appreciate that embodiments in accordance with the present invention may be implemented in a very wide variety of ways. This application is intended to cover any adaptations or variations of the embodiments discussed herein. Therefore, it is manifestly intended that embodiments in accordance with the present invention be limited only by the claims and the equivalents thereof.
